In today’s manufacturing landscape, the precision of sheared and cut plates is paramount to product quality and cost-efficiency. As the demand for high-quality products increases, the need for accurate cutting in shearing processes also grows. Utilizing a shearing machine with high-precision positioning can significantly enhance economic benefits.

Challenges in Traditional Automated Shearing Lines

Automated shearing production lines typically comprise a heavy-duty decoiler, a leveling machine, an NC servo feeder, and a shearing machine. These systems are generally suited for materials with low positioning accuracy requirements. However, several limitations hinder their effectiveness:

  1. Structural Limitations of Traditional NC Servo Feeders: Traditional feeders use single pressure feeding rollers. Over time, these rollers can wear out, leading to uneven changes in diameter. Additionally, thickness variations in the material can cause diagonal errors in the sheared output.
  2. Accumulated Cutting Deviations: As material is fed from the same coil, cutting deviations accumulate, eventually disrupting normal operations. Frequent machine stoppages for manual error correction not only affect product quality but also reduce cutting speed.

Introducing the Dual-Servo NC Feeder for Enhanced Precision

To address these challenges, a new dual-servo NC feeder has been developed. This feeder, based on traditional models, features two symmetrical and independent servo feeding systems. Each system includes components such as a frame, servo motor, servo driver, transmission gears, active and passive wheels, main drive shaft, and a photoelectric position sensor, all controlled by a PLC.

Advantages of the Dual-Servo NC Feeder

  1. Symmetrical and Independent Feeding Mechanisms: The dual-servo feeder shifts from a single to two independent feeding mechanisms. This design replaces the original integral pressure roller with split pressure rollers on both sides.
  2. Improved Cutting Precision: Sensor tracking and PLC control maintain the diagonal error of the sheared material within permissible limits. This eliminates errors that were previously uncorrectable with traditional feeders.
  3. Automatic Correction Capabilities: Even as feeding rollers wear out, the unique detection method and robust servo system software ensure consistent cutting precision.
  4. High Material Transfer Speed: The dual-servo NC feeder not only corrects errors automatically but also supports high material transfer speeds, making it ideal for modern high-precision processing.


In the competitive field of manufacturing, precision and efficiency are critical. The dual-servo NC feeder represents a significant advancement over traditional feeders, offering enhanced precision, automatic error correction, and high transfer speeds. By integrating this innovative technology into automated shearing lines, manufacturers can achieve superior product quality and greater economic benefits.
